YooC activity tracker makes a game out of exercise

Inside every person who wants to become more active is a struggle. There’s the gung-ho, motivated you, and then there's the you who would rather plop on the couch with a pint of ice cream.

The YooC fitness tracker, seen at CES15, pits the two "yous" against each other in a fitness challenge where the only competitor is, well, you. "Active you" earns points when you’re moving—but stay sitting too long and "inactive you" gains points.

The tracker is tiny, about the size of a quarter, and can be worn anywhere. It has a 25 “false step” filter to improve accuracy. To help you get into the habit of moving, Yoo Fitness is hosting a contest it calls Yoo Challenge Route 66.
